Clementi spent much of his life in England, though it was in Vienna that he had a musical ‘duel’ with Mozart. Cramer, Meyerbeer, Hummel, Berger and Moscheles were among his pupils, as was Field, who effectively became his assistant. Haydn’s visits to London provided public competition but led to genuine friendship. Ever the businessman, Clementi persuaded Beethoven to let him become his British publisher. Moscheles, who had studied with him in London, was one of the pallbearers at his funeral.
